Question

COS-1 1/2 +2sin-1 1/2 का मान है​

Answer 1

Answer:

2Pi/3

Step-by-step explanation:

Cos^-1 1/2 + 2 sin^-1 1/2

This can be written as

(Cos^-1 1/2 + Sin^-1 1/2) + Sin^-1 1/2

= Pi/2 + Sin^-1 1/2 (Cos^-1 x + Sin^-1x = Pi/2)

= Pi/2 + Pi/6 (Sin-1 1/2 = Pi/6)

= (3Pi+Pi)/6

= 4Pi/6

= 2Pi/3
